A mother greets her two sons as they arrive home. Two women, the boys and a gentleman visitor have tea. The man leaves.

The mother leaves her baby in a high chair at table and goes out. The boys paint a moustache on the child and put a hat on his head. His mother returns. The boys hide on the stairs and see the maid talking to a man. They are caught by their father.

The boys come into the room looking rueful, having had a beating, then laugh as they remove the cardboard from their trousers.
